  The present application are highly reproducible poly(propylene glycol fumarate) compositions having a controlled end group ratio and range of molecular weights with minimal low molecular weight and excessively high molecular weight fractions, and methods for their manufacture. These compositions, having a preferred weight average molecular weight (Mw) of between about 500 and 3000 and a number average molecular weight (Mn) of between about 300 and 2000, are especially useful in biomedical applications such as in bone cements and tissue implants or glues. In the preferred embodiment, the polymer is prepared from propylene glycol (PG) and fumaric acid (FA) by one of three methods: melt polymerization using non-volatile starting materials; step polymerization where in each step the polymer is increased by the addition of two groups to the polymer ends; or under reaction conditions maintained so that only the condensation byproduct, water, is removed during the reaction, thereby keeping the ratio between PG and FA constant. Variations of the PPF polymers include polymers with increased sensitivity to hydrolysis through incorporation of lactic acid groups into the polymer and polymers formed from maleic acid, maleic anhydride, citraconic acid or citraconic anhydride.

  本申请涉及具有受控端基比率和分子量范围（低分子量和过高分子量馏分极少）的高重现性聚（丙二醇富马酸盐）组合物及其制造方法。这些组合物的优选重量平均分子量（Mw）在约 500 到 3000 之间，数量平均分子量（Mn）在约 300 到 2000 之间，特别适用于生物医学应用，如骨水泥和组织植入物或胶水。 在优选的实施方案中，聚合物由丙二醇（PG）和富马酸（FA）通过以下三种方法之一制备而成：使用非挥发性起始材料进行熔融聚合；分步聚合，在每一步中，通过在聚合物末端添加两个基团来增加聚合物；或在反应条件保持不变的情况下，在反应过程中只去除缩合副产物--水，从而保持 PG 和 FA 之间的比例不变。 PPF 聚合物的变体包括通过在聚合物中加入乳酸基团而提高水解敏感性的聚合物，以及由马来酸、马来酸酐、柠康酸或柠康酸酐形成的聚合物。
